 The molecular analysis of the egg clutches allows the “taxonomic and phylogenetic studies of the cephalopod species as a whole.”

Researchers also have used the common bobtail to test variability and mutation of cephalopods due to their widespread abundance, in where they have found the arms of the common bobtail having many anomalies.Determining the age of a common bobtail is found through the analysis of the statolith.The statolith on a common bobtail squid is small, with a size of 0.41mm to 0.57mm.
